Find the perfect size for your face

Choosing the ideal frame for your new sunglasses or eyeglasses is a matter of millimeters: a perfect balance between style, everyday comfort, and correct vision. The right size glasses should rest on the nose without squeezing, remain stable on the ears, and perfectly center your gaze over the lenses, ensuring visual comfort that lasts all day.
Here are two foolproof methods to find your ideal size in just a few seconds.

"Choosing the size is the first step, but our know-how ensures that every millimeter is in the right place."

3 - Check the position of the paper
The measurement is determined by marking the point where the opposite edge of the card aligns with your eye.

A - Medium size (suitable for most people)

If the edge of the card aligns with the outer corner of your eye. This corresponds approximately to the following eye sizes: 51-52-53-54


B - Large size

If the edge of the card is between the outer corner and the center of your eye. This corresponds approximately to the following eye sizes: 55-56-57-58


C - Small size

If the edge of the card extends beyond the outer corner of your eye. Approximately corresponds to the following sizes: 47-48-49-50


- Compare the measurements with your glasses

If you already have a pair of glasses that you feel comfortable with, the solution is literally written on the frame.
Check the inside of the temples: you'll find a series of small numbers engraved (for example: 52 18 140).

Compare the measurements with your glasses

The first alphanumeric code indicates the model code (e.g., XY 2140), then we have:

- The lens width (caliber): indicates the horizontal width of a single lens. This is the value that determines whether the glasses are Large, Medium, or Small.

- Bridge width: represents the space between the two lenses. It is essential to ensure that the glasses do not slip on the nose.

- Temple length: indicates the total length of the temple, from where it attaches to the frame to the tip.

Each of these numbers is measured in mm.
Comparing these values with those shown in our product sheets will ensure a familiar and comfortable fit.

FAQ - Frequently asked questions about glasses sizes

Size is usually engraved on the inside of the left temple or on the bridge (the part that rests on the nose). You'll find a sequence of three numbers separated by a square or a space, for example: 52 18 140. The first indicates the lens width, the second the bridge, and the third the temple length.
A difference of 1 or 2 millimeters in size (lens width) is often imperceptible on the face. However, if you have a very narrow or very wide face, we recommend staying as narrow as possible. As close to your usual size as possible to ensure your eye remains centered on the lens.
Yes, the bridge determines how the glasses sit on the bridge of your nose. If the bridge is too narrow, the glasses will tend to sit too high; if it's too wide, they will constantly slide down. If you have a thin bridge of your nose, look for sizes between 15 and 17 mm; if it's wider, the bridge will be between 15 and 17 mm. wide, oriented on 18-21 mm.
Some models are produced in a "Standard" (or One Size) version designed to fit most faces. However, larger models are available. Iconic designs often offer multiple options (Small, Medium, Large) to ensure tailoring precision for each customer.
The general rule of style is that the top of the frame follows the natural line of your eyebrows, without covering them completely. This allows you to maintain the expressiveness of your face. If the glasses rise too high above your eyebrows or cut them in half, you'll notice a slight difference. It may be too large for your bone structure.
